[PATCH] gpio: Mark xtensa gpio driver as BROKEN

[Guenter Roeck <linux@xxxxxxxxxxxx>]

xtensa:allmodconfig build fails with

drivers/gpio/gpio-xtensa.c: Assembler messages:
drivers/gpio/gpio-xtensa.c:87: Error: unknown opcode or format name 'read_impwire'
drivers/gpio/gpio-xtensa.c:110: Error: unknown opcode or format name 'rur.expstate'
drivers/gpio/gpio-xtensa.c:124: Error: unknown opcode or format name 'wrmsk_expstate'

Tests with various compiler versions was unsuccessful, suggesting that the
assembler instructions may only be available with some unspecified xtensa
variant. Until that is resolved, mark the driver as broken to enable test
builds.

I know this is likely controversial, but it seems to be better than letting
builds fail. And maybe it causes a real fix to be submitted.
